Voice VLAN Configuration

Configuration Prerequisites

Create the corresponding VLAN before configuring a voice VLAN.
VLAN 1 (the default VLAN) cannot be configured as a voice VLAN.
In case a connected voice device sends VLAN-tagged packets, ensure that the voice VLAN created on
the switch is consistent with the VLAN corresponding to the VLAN tag carried in voice packets.
Otherwise, the switch will not be able to properly receive voice packets.

normal).
The source MAC address of the packet is not
